Detailed Description
ISO C++ 2014 namespace for suffixes for duration literals.
These suffixes can be used to create chrono::duration values with tick
periods of hours, minutes, seconds, milliseconds, microseconds or
nanoseconds. For example, std::chrono::seconds(5) can be written as 5s
after making the suffix visible in the current scope. The suffixes can
be made visible by a using-directive or using-declaration such as:
• using namespace std::chrono_literals;
• using namespace std::literals;
• using namespace std::chrono;
• using namespace std;
• using std::chrono_literals::operator''s;
The result of these suffixes on an integer literal is one of the
standard typedefs such as std::chrono::hours. The result on a floating-
point literal is a duration type with the specified tick period and an
unspecified floating-point representation, for example 1.5e2ms might be
equivalent to chrono::duration<long double, chrono::milli>(1.5e2).
